they dont sting, they bite.
Some ants sting, but there are thousands of species that do and don't sting. Most "stinging" ants actually bite, although some ants have a stinger as well. Nearly all red ants sting (or bite). Some other black ants sting, but it is hard for the average person to tell between them.

Ants sting rather than bite. The common black garden ant in the UK doesn't sting people, but they do have ants that will. These include wood ants and flying ants. Another ant in Britain that stings people is the red ant.
Not all ants have sting. Those species of ants that have a sting in the end of their abdomen can sting whether it is a worker or a queen. The only member of such species that can't sting is the male ant whose only purpose in the colony is to fertilise the queen or gyne during the nuptial swarm.

All ants bite or nip if you like with their mandibles which are capable of delivering a poison. Personal experiences: Yes, it is true. My wife was bitten by a common black ant and I white pimple appeared with some redness. I never thought that they would bite because I have neven been bitten by a common black ant. A red ant, absolutely. The Texas red ant which is huge, has bitten me and it really did sting and hurt. My ankle swelled up. Over a few days, the swelling disappeared and all was well.
